76. Penthestes hudsonicus (Forster) Brown-headed Chickadee 
Two chickadees with characteristic Hudsonian notes seen near Kenni- 
cott, May 10. Species noted several times en route to Huorick’s camp 
and later found fairly common in all lower spruce forest, even to limit of 
timber at Trail End. Like most chickadees very secretive at nesting time 
and their lackadaisical call, “Si-da-daa!” , became much commoner in woods 
after young were abroad. First juveniles taken July 11. 
Specimens: Seven adults, June 2 to July 6. Three juveniles, July 11 and 12. 
These birds noticably greyer above (less brown) than P. h. hudsonicus from northern 
Ontario, and obviously referable to columbianus. 
77. Regulus satrapa Lichtenstein Golden-crowned Kinglet 
Not common, but found breeding in two of coolest, gloomiest, wooded 
canyons at low elevation. On June 17 a female in laying condition taken, 
and on June 29 a singing male secured at same spot — doubtless same 
male with a new female, for a pair seen. After nesting birds were met 
with more commonly. Not early nesters here, no juveniles being seen on 
wing until July 22. 
Specimens: Four adults, June 29 to July 15. Four juveniles, July 22 to August 14. 
All have bright green mantles and are referred to R. s. olivaceus. 
78. Regulus calendula (Linnaeus) Ruby-crowned Kinglet 
Common on lower Chitina and several heard in song May 12 and 13, 
but apparently did not reach upper part of valley in spring. August 15 
when bird appeared at Hubrick’s camp and only a single individual seen. 
Specimen: Adult male, May 13. 
Typical R. c. calendula. 
79. Myiadestes townsendi (Audubon) Tow t nsend’s Solitaire 
Solitaire found very sparingly along timbered slope at fairly high 
elevation. Its penetrating call note, “ Tink ! Tink!” that suggested a 
little the “ Peet !” of olive-backed thrush, heard occasionally, and its loud, 
rich, ringing song sometimes filled the woods. A song that suggested 
western tanager, robin, and rose-breasted grosbeak all in one. Like most 
other species occupying this range, found in last patch of spruce at Trail 
End — this observation July 28. Extremely difficult to find bird in rough 
country and only two males secured. A juvenile seen at Hubrick canyon 
August 6 and 7. 
Specimens: Two, June 16 and July 4. 
80. Hylocichla ustulata (Nuttall) Olive-backed Thrush 
Very common. Its tender song first heard May 27 at camp and in 
a few days species numerous and woods filled with soulful melody. Most 
numerous at river-level. Its sharp call note, “Peet!” or “Peent!” , first 
answer of alarm to sound of decoy squeak. Woods vocal with thrush 
music at all hours of day and most of night, there being but a short period 
of quiet from near midnight until about 2 a.m. — this at height of song 
during longest June days — but song season closed with a strange abrupt- 
ness about July 15. On May 30 a bird timed, gave regularly ten songs 
a minute at 10 p.m.
